Unnamed 1990 North Indian Ocean Cyclone
● Data reliability: ReliableWeather satellites monitored it throughout, so its track and intensity are relatively accurate (Atlantic and E. Pacific since 1966, other basins since 1980).
未命名 at 1990-05-03 20:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为Super Cyclonic Storm, max wind 约 64.3 m/s (1 分钟平均) , minimum central pressure 920 hPa, at 1990-05-11 14:00:00前后结束, total 记录 32 track points (6 h一个) . 曾Landfall或贴近land.

This system has no official Chinese name, so the English name is used. Intensity is classified by the local agency in the relevant sea area, converted from 1-minute sustained wind using the WMO factor, for reference only. Data notes · Incorrect translation?
